These belts, which take their name from the shape of the sergeant crest, are conveyor belt types with "V" or "U" shaped patterns as a profile on the belt. These belts, which are in the class of profiled belts, are used to transport moist or bulky materials, as well as granular materials upwards at a certain angle. Profiles on the belt, generally on 250-350 angled conveyors, help to carry as much material as possible by preventing the materials from sliding down. There are different production patterns related to the product and technical drawings are on the next page.
